Outlook for Biogas and Biomethane Introduction to biogas and biomethane
Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment. Its precise composition depends on the type of feedstock and the production pathway. The methane content of biogas typically ranges from 45% to 75% by volume. Biogas is usually produced using the following technologies: Biodigesters: These are airtight systems (e.g. containers or tanks) in which organic material is broken down by naturally occurring micro-organisms. Contaminants and moisture are usually removed before use of the biogas. Landfill gas recovery systems: The decomposition of municipal…

Fatih Birol
Executive Director. As Executive Director of the International Energy Agency, Dr Fatih Birol (@fbirol) has positioned the IEA at the forefront of global efforts to advance a secure, affordable and sustainable energy system. Since taking office in 2015, he has modernised the Agency by broadening its energy security mandate beyond oil to include electricity, natural gas, renewables and critical minerals, strengthened the Agency's global leadership in clean energy transitions and expanded IEA membership to include major emerging countries. As a result, the IEA’s share of global energy demand coverage has increased from 40% to over 80%. He has also played a central role in the global response to major energy security emergencies, including those triggered by the invasion of Ukraine in 2022 and the 2026 Strait of Hormuz crisis.Dr Birol joined the IEA in 1995 and steadily rose through the ranks from junior analyst to Chief Economist, where he oversaw the flagship World Ener...
